MECHANIAL MOTOR.

SPECIFICATION forming part of Letters Patent No. 228,098, dated May 25,1880. Application filed January 12, 1880.

thereon, which form a part of this specification.

This invention relates to certain improvements in motors adaptedespecially for domestic use, its object being to provide a cheap,compact, durable, and efficient automatic motive mechanism which maybeutilized for driving various household apparatus, such as churns,cradles, fly-brushing machines, sewing-machines, and other implements.

My invention consists in a novel combination and arrangement of devices,whereby the motor is readily connected to different machines and asmooth and uniform movement is secured. l

The accompanying drawing represents a perspective view of my improvedmotor.

The letters A A indicate two upright plates, in which are formed thebearings of the various arbors of the train of gear-wheels, the-lowerends or feet of these plates being secured to the bench B, and theirupper ends connected by a cross-bar, (l. Tothe shaft d of the main wheelD, between the lower ends ofthe plates A A', is secured the inner end ofa coiled motive spring or springs, the outer end of which is secured tothe inner periphery of a barrel, D', which is firmly fixed to the innerside of the plate A. The top shaft, E, of the train carries at one ofits projecting ends a cranki wheel, F, and at its other end abalance-wheel,

G. The crank-wheel F has through it a slot,

i h, extending from near its center to near its periphery, and in thisslot is arranged an adjustable wrist-pin, t', with which is connectedthe pitman J, having its opposite end, in the present instance,connected, by means of a screw-pin, j, and thumb-nutj, with thereciprocating dasher-rodK of a churn, the upper end of the saiddasher-rod projecting through a guide-bearing, Z, carried by anadjustable arm, M, which is secured to the cross-bar U by means of ascrew, m, setting through a slot, m. By means of the adjustable arm Maudscrewpinj the reciprocating flasher-rod or any other similarreciprocating device may be connected with the motor at varyin gdistances therefrom. The balance-wheel Gr has arrangedat one side auextra weight, g, and the wheel is so keyed upon its shaft as to bringthis extra weight on the opposite side of said shaft from the connectionof the pitman J with the crankwheel, in order to balance the shaft andgive the pitman and its connections a uniform motion. On therearwardly-projecting portion of the shaft d of the main wheel isarranged a gear-wheel, N, which meshes with a pinion, O, carried by ashort shaft having at its end the crank P. By means of this crank andthegearwheel and pinion the spring is wound up.

Outside the gear-wheel N, on the main shaft, is iixed a fusee, Q, towhich is connected a cord, R, passing upward and over a pulley, S, whichmay be secured to a cross-beam, ceiling, or other object, and hasattached to its dcpending end a weight, T, which may be heavier orlighter, as desired, to control the speed of the machine. The object ofthis fusee, its cord, and weight is to give a uniform speed to themotor-train, the cord being upon and unwinding from the smaller portionof the fusee when i the spring or springs are wound up completely, andgradually unwinding from a larger diameter of the frame, and exerting agreater force upon the shaft as the spring' or springs by unwindingspend their force. Thus the increasing power of the fusee compensatesthe decreasing power of the spring or springs.

The letter U indicates a brake-arm pivoted to the plate A, and havingits free end provided with pad u, of leather or similar material, in'position to be swung against the periphery of the balance-wheel.

By locating the motive spring or springs, its inclosing-barrel, thewinding apparatus, and regulating-fusee at the lower end of the motivetrain, I give the motor a iirm base and steadiness of action which itwould not otherwise have, and by mounting the motor upon the roo bench Bit is placed in position to be readily connected to almost any machineof ordinary domestic use.

It will be obvious that a cord and weight may be used in lieu of thespring` as a prime motoi for rotating the shaft d, and in this case theportion of said shaft between the front and rear supporting-plates, A A,should be formed as a Windlass, to which the cord may be attached andpass over av pulley to a weight.v

' When a cord and weight are thus used the fusee and its cord and weightmay be dispensed with.

What I claim is- The combination, with the motor-train below, of theshaft E, geared with said train and carrying at one end thebalance-wheel G, having an eXtra weight on one side, and at the otherend the wheel F, having slot h, the pitman J, having pin i, adjustablein said slot, the piston K, having its intermediate portion adjustablyconnected to the lower end of said pitman, and the adjustable arm M,having the guide-bearing Z, embracing the upper portion of said piston,substantially as described.

In testimony that I claim the foregoing,` as my own 1 have heretoaffixed my signature in presence of two witnesses.

A NOAH J. MILLER.
